MarmitakoeuMarmitakoes

Also: Marmita, Sorropotún, Tuna and potato stew

A Basque fishermen's stew of fresh tuna and chunked potatoes simmered in a sauce built on sweet dried choricero pepper, onion, and green pepper.

Identity criteria

1Fresh tuna (bonito del norte / albacore) added at the very end so it barely cooks and stays moist
2Potatoes broken (cachelo) rather than cut so their starch thickens the broth
3Pulp of dried pimiento choricero peppers gives the signature sweet-earthy base
4Built on a sofrito of onion and green pepper, no cream or roux
5A brothy stew, not a dry braise — eaten with a spoon

TomatooptionalSome versions add a little tomato to the sofrito

Sofrito: Slow-cooked onion and pepper build the savory-sweet backbone before liquid is added
Cracking potatoes: Tearing chunks ruptures cells so released starch thickens the stew naturally
Carryover poaching: Tuna is folded in off or near the heat so residual warmth cooks it just to set, keeping it tender

Choricero pepper pulp → Mild ñora pepper or sweet paprikaadmissible
Approximates the sweet-pepper base if choricero is unavailable
Bonito/albacore → Other firm fish like swordfish at a pinchadmissible
Changes character but stays a tuna-style stew
Fresh tuna → Canned tunainadmissible
Loses the fresh, just-set texture that defines the dish
Cracked potatoes → Cornstarch-thickened brothinadmissible
Destroys the rustic starch-bodied identity

Boiling the tuna so it turns dry and stringy
Slicing potatoes cleanly instead of cracking them, leaving a thin watery broth
Skipping the choricero pulp and relying on tomato, which loses the signature flavour
Using canned tuna and calling it marmitako

A working dish of Basque and Cantabrian tuna fishermen, originally cooked aboard boats in a pot (marmita) during the summer bonito season.
